Think you're ready to make the switch to HDTV? Before you head out to buy a television set that is certain to become the most valued piece in your home entertainment system, it is a good idea to make sure you know what you're looking for. There are actually different types of HD televisions, so taking the time to know what you're looking for is a good way to make sure the TV you ultimately purchase will suit your needs.

First, let's examine the difference between HDTV and HD-Ready TV. An HDTV is a television set with the ability to receive HD signals over the air. In order to receive those signals, you may need an antenna; however, the HD tuner that is built into the TV has the ability to process the HDTV signal without the need to purchase any other additional equipment. In order to receive an HD signal from your satellite or cable provider; however, you will need to acquire a proprietary set-top-box from the provider.

With an HD-Ready TV you will need to purchase an extra piece of equipment in order to be able to receive the signal. For example, you would need a stand-alone HD tuner. Another option would be to use the set-top HDTV box that is provided by satellite and cable providers.

In addition, you need to be aware of the different choices that are available when it comes to HDTV. When you go out to buy your first HDTV you are going to need to give some thought to the best delivery method for your needs.

The first decision you will need to make is the type of screen that you prefer. One option is a CRT; which stands for Cathode Ray Tub. You are already familiar with this type of screen even though you may not be aware of it. This is the most traditional type of television screen. Another option is a rear projection television. In the past these types of televisions were actually based on the same technology as CRT; however, today LCD technology is replacing that. You can usually find rear projection televisions in much larger sizes than CRT.

The newest members of the High Definition family are flat panel televisions. There are also two different choices to choose from here as well. They are LCD and plasma. Plasma televisions use gas that is sealed inside plasma right in the cells on the television screen. The picture signal charges the gas and causes it to change colors. The picture is formed as a result. LCD, on the other hand, utilizes liquid crystals instead of gas.

It is important to keep in mind that there are a few critical differences between LCD and plasma HD televisions. With plasma HD televisions, you will typically be able to find larger screen sizes. In addition, these TVs will generally have improved color accuracy as well as motion tracking. The one drawback with plasma is that they tend to produce more heat than other types of HD televisions. LCD High Definition televisions do not produce as much heat and also typically offer a longer life than plasma televisions.
